Description

Technical Field

[0001] The utility model relates to the technical field of anti-rust bags, in particular to a sealing and film cutting device for anti-rust bags. Background Art

[0002] After the anti-rust bag uses this film to package and seal the anti-rust items, the VCI contained in the film begins to sublime and volatilize anti-rust gas factors, which diffuse and penetrate into the surface of the anti-rust items and adsorb on them, forming a dense protective film layer with a thickness of one molecule, isolating the various factors that induce rust from contacting the surface of the anti-rust items, thereby effectively preventing the occurrence of rust. Iron metal, alloy steel, cast iron, copper, brass and bronze, electroplated metal, zinc and alloys, chromium and alloys, cadmium and alloys, nickel and alloys, tin and alloys, aluminum and alloys, stainless steel and other metal materials and products, anti-rust bags need to be sealed during processing, and sealing and cutting are performed at the same time. Most of them need to be placed on the device manually, which is inefficient and labor-intensive.

[0003] For example, the Chinese patent with publication number CN213650127U proposes a feeding mechanism for an anti-rust bag sealing and film cutting device. The component twists a hand valve through the action of external force, and the hand valve drives the sliding block to slide inside the left side of the workbench. Since the sliding block is connected to a spring, and a card block is connected to the top of the spring, the card block can be extended and retracted inside the sliding block with the cooperation of the spring. Since the card block is arranged in an arc shape, the card block can be engaged and separated from the external plate, thereby achieving a good disassembly and installation effect, greatly improving the flexibility of the device, and facilitating the installation and disassembly of anti-rust bag sealing and cutting devices of different sizes. By setting a traction machine connected to the discharge port to pull it, the guide roller, the first roller, and the second roller are located at different horizontal planes, which respectively guide the anti-rust bag to rotate and prevent it from directly contacting the inner wall of the main body, and at the same time can stretch it. The right end of the main body is movably connected with a first screw rod, the lower end of the first screw rod is clamped with an extrusion column, and a workbench is arranged at the right end inside the main body. Since the second roller and the extrusion column are respectively fitted with the workbench and the extrusion column sleeve is provided with a sponge air cushion, the anti-rust bag can be pressed and the air can be expelled at the same time to avoid uneven sealing of the anti-rust bag when cutting it later. However, in this scheme, the air is squeezed out by the extrusion column, but the air may still enter the bag during cutting and affect the cutting effect. For this reason, we propose a film cutting device for sealing anti-rust bags. Utility Model Content
